I fail to see the point of this. What is the advantage over a normal I/O setup? $70k will get you some sick big blocks and worked Bravo drives.... With enough money left that you could still buy a pretty nice boat to put them in.

People using these need outboards. Think off-shore large fishing boats.

That said, I can not see where they come up with 70k for these outboards. From what I've read, the GM LSA crate motor can be had for around 15k with all electronics. How much does it REALLY cost to make it into an outboard? Sounds like there is quite the markup in price; I understand profit and paying for R&D, but 70k sounds like a lot.

When I think off-shore large fishing boat I think inboard... Like a 38' Chris Craft Command Sportfish with twin 427 Fords. I'm not a fisherman so maybe I don't understand and advantage of big outboards on the ocean.

I have no idea on cost. Have you ever been out on one? They accelerate to 60 mph WAY faster than I thought a 42' 23k lb boat would.

We don't have a whole lot of these where I'm at, but I could only imagine with all that power!

And to answer the outboard vs I/O deal, it seems much easier to replace a salt water ridden outboard motor after ten years than an I/O, not to mention cheaper too. I'm willing to bet two 8.2l merc ho's with bravo 3x drives are no less than 4 ob's, if not more. And less power.

There are plenty of Commanders with original blocks and heads in salt. We're talking 40-50 year old boats kept in salt. Simple solution to that, if you're concerned, is fresh water cooling. It's cheap compared to the cost of a new engine. Then you're only replacing heat exchangers every decade or two. I don't see the advantage of an eggbeater unless you're talking about a very small runabout or operate in shallow hazardous water.

Saw one of these being built at MC about a week ago... nuts! i'm willing to bet Yamaha's would still be about $20k-$30k cheaper for four.

MSRP for the Yamaha 350 is $30k each but can be had for $23k all day. As with any outboard just add two zeros to the HP and you get a close MSRP price (i.e. 150HP = $15k approx MSRP). I guess as with any big baller boat money is no object and I guess running two 557HP outboards is probably less headache than maintaining 4 outboards running wide open. A few of my friends that run big single motors in their 28-30 foot tunnel boats said they'll never run 2 small motors again in the same size boats.
